A Model Context Protocol (MCP) server that gives coding agents fresh, cited documentation for a curated Cloudflare developer stack. It's backed by Cloudflare AI Search and queried through the ai_search_namespaces binding.

The server exposes two read-only tools, one to discover what's available and one to search it:

The stack spans Cloudflare's own docs, API, blog, and community, plus popular tools used alongside them. Each library maps to a ?libs= slug you can use to scope the server (see below):

The /mcp endpoint accepts a libs query param to scope the server to a subset of the stack (using the slugs above), e.g.:

https://stack.mcp.cloudflare.com/mcp?libs=cloudflare,hono,vite

When scoped, list_libraries and search_dev_stack (including its library enum) only expose the selected libraries, and cross-stack search is limited to them. Unknown slugs are ignored, and an empty or all-invalid libs falls back to the whole stack.

Scoping is read from the connection URL on every request, so it applies whether the client connects to /mcp or the /sse alias.

Connect an MCP client directly to https://stack.mcp.cloudflare.com/mcp using Streamable HTTP. The /sse path serves the same stateless transport for backward compatibility.
